Remove side deco strips to remove screws that hold to cabinet. Pull microwave out and set on saw horses (power cable should be long enough to do this). Remove screws to top cover and lift enough to remove all connectors from the front panel pcb. Remove grounding wires from next top lid. Remove connectors from transformer on rigt side and the two connectionss at the rear fan assy. Remove top cover/vent assy. Remove the next top cover to get access to the light bulb assy. Use a cloth or kleenex while handling the new bulb as you replace it. The clip thta holds the bulb is easily released and use reverse procedure when assembling. For springs those can be replaced without removing the microwave from the cabinet. Remove the 2 screws that hold the door together accessed from the inside of the door at top. Pull door up to release from the clip at the bottom. Remove the broken spring and replace with new one. Use a screwdriver to help twist the torsion spring to clip into place. Replace door assy in reverse order.

Microwave glass turntable when pop

After popping the last few kernals of popcorn, we hear a different kind of pop sound come from our microwave oven. When we looking inside, we found that the glass turntable had broken unevenly in half. Although we didn't understand why it had happned, we did know we'd be without the use of the microwave without a new one. After less than 10 minutes surfing online, I had found the correct part on PartSelect.com and had arranged to have it shipped to me by speedy delivery. Once it arrived, I just popped the new turntable into the microwave and used the box to dispose of the broken one. It could not have been easier and it saved me the cost of a service call and likely further delay.

My unit is a wall mount/cabinet/built-in model. The repair is actually fairly simple once you determine that the actual microwave is just a component of the entire unit, and that it (the microwave) can be easily removed from the unit. I did not figure this out until after I removed the entire unit (disconnect the power supply, lift the entire bulky, heavy unit out of the cramped space in the cabinet, etc). Once I got it out I figured out how easy it is to remove the actual oven - a couple of screws, literally. The unit is a bit bulky, but not particularly heavy and is quite manageable. I did this entire process alone.

I got the oven out, rolled it on it's side and found the plate to access the motor. The plate is located on the bottom/underside of the unit. The plate is nothing more than a section of the underside of the metal housing that has been cut-out as an access point. This "cut-out" is not complete - that is, not completely cut out so as to all the plate to stay in place without the need for screws, etc, until you actually have to use it. I used a pair of dykes to cut the couple of points still connecting this plate, removed the two phillips screws to remove the motor, disconnected the two wires connected, then reversed to complete the repair. You then flip the cut-out plate over/rotate it, and some screw holes line up. Find a couple of small screws, and re-attach the plate to cover the motor.

The actual fix is really easy, again, once you figure out the simple way to remove the oven. I am an idiot, so you will probably find this much easier. I could probably do this repair now, after my experience, in less than 30 minutes (probably less than 15 minutes). I probably save a couple hundred $ by doing it myself so was well worth the time to do it. Good luck.

Scratches in Surface

This product comes in a bottle with a brush like Liquid Paper. It goes on incredibly easy. A second coat might be needed. I wanted to prevent rust from setting in so I covered the scratches and dings. The paint is a little brighter since my washer is 10 years old but it still looks great.

Tension spring replacement

Here's a 21st century tip for all repairs: Get out your cell phone and take pictures of the steps as you go so you'll always have a reference if you forget something.

The replacement of the tension spring is easy. Getting there is the hard part. First, you need to remove the grill between the oven and microwave doors. There are 2 screw in the center and one on each end. Then just pull it away from the oven. This allows access to the the two clips that hold the bottom of the door on.Next, remove the 2 u-shaped clips on the bottom of the door on both sides. 1 screw each. The bottom of the door will be loose, so be careful on the next step.Open the door. Clamping the outer part of the door and the inner part with one hand, remove the 2 screws on the the inside of the door cover. They are closest to you at 10 and 2 o'clock. The outer door trim will now come off. Put it aside and close the door. On the bottom of the door frame, locate and remove 2 more screws about 6 inches from the ends and the inside plastic cover will be free to remove.Now you will be able to remove the broken tension spring by lifting and threading it out of the groove it sits in. Replace with the new tension spring by threading the looped side into that groove first and criss-crossing it over the other tension spring. Then locate the hole on the opposite hinge and slide it in place. This will lock it in. Reverse the procedure for putting the door back together as you did removing it. You may want to get someone to help you hold the door open considering the new spring will snap it shut without the weight of the door on it. After you reassemble the door, replace the vent grill between the doors and you're done.

Door right-side torsion spring snapped.

The KitchenAid stainless steel microwave model appears to be a bit different from other install instructions posted:

1) Removing the two inside-door screws will completely release the fairly heavy exterior door panel from two holding clips at the bottom of the door unit. So BE PREPARED and HOLD THE DOOR HANDLE while removing the two screws or panel will crash to the floor. Fortunately I did. Consider help to hold and "catch" the exterior door panel.2) The inside-door (which the exterior door is attached to) has a plastic frame that needs to be removed to gain access to the springs. However, removing the two screws holding the plastic frame located in the bottom-edge of the inside-door required removing stainless steel framing around the sides and bottom of the MW unit. This additional SS framing around my microwave/oven combo might be the result of a custom cabinet install.3) Inserting the spring (torque tension rod) was a bit tricky using screw driver and needle nose plyers to hold and twist both ends into place. Again, a second set of hands might help. At this point, the door spring action feels too strong but when re-installed, the weight of the exterior door will normalize this.4) Re-install plastic frame, SS cabinet framing if applicable, exterior door centered onto holding clips, and you should be finished. Check that two screws in step # 1 holding exterior door are tight without stripping to ensure your repair job doesn't result in the exterior door crashing to the floor following normal use.5) In all, the spring cost $45 w/tax and 3-day delivery and the repair time was about 30 minutes vs. repair estimates starting at $129.

This is the second time this has occurred. The first was still in original warrenty. It took two Sears servicemen to dis mantel and obtain access to the bulb. One had to hold it up in the cabinet while the other took off the tope to get to the bulb. I purchased an additional extended warranty for three more years but when I called this time they said that light bulbs were not covered. I had to furnish the bulb and they would install it for free. I am waiting for them to come and do it again. Your price even with shipping cost was cheaper than ordering the part from Sears.

Microwave Turntable Won't Rotate

I turned off the power to the oven at the breaker. I then removed the side trim pieces by removing the screws located behind the lower oven door. I removed the plastic trim pieces above and below the microwave oven and removed the control panel and slid it into the opening above the microwave. I located the two screws securing the microwave into the frame and began sliding it out. I had to disconnect a small wiring harness and two wires from the microwave that were attached inside the opening above the microwave. The microwave section was the easily slid out, turned on it's side where the turntable motor was accessed by removing the access panel. I pulled the old motor, checked resistance and it matched the new motor. I then checked the old motor by applying 120V to it and it ran FINE! I thought I had the wrong part, but decided to install the new motor anyway. I did, secured the access panel and replaced the microwave in the frame. I reconnected the wires and secured the control panel and tested the microwave...and the turntable works!

repalced bulb.

The instructions from another customer was helpful. I concur with another comment I read while researching this proceedure. What Idio-- would design a microwave that required pulling the unit from the wall and removing the top panel just to access. It is good idea to unplug the transformer and capacitor wires before proceeding. I also googled a schematic to see the parts layout. Remember not to touch the bulb with your fingers. Use a cloth or paper towel.

Door spring broke (spring lightens the door when opening/closing)

Just had to remove the screws holding the outer part of the door on (didn't have to take off the entire door). Using the other door spring (most models have two that cross) as an example, the new spring was fairly easy to place. Only problem is that the new spring was made from a smaller gauge metal and is not nearly as strong as the original, making the door feel heavier when opening/closing than before. The difference with and without the 2nd spring is barely noticeable. Had I known that they were making the parts cheaper now, I would'nt have bothered fixing it at all.

Door spring broke

Open the door and removed the 2 screws that hold the frontglass and stainless steel panel (Hold on to the door handleor the face and glass will come crashing to the floor; learned this after the first time a couple of years ago $$$). Set the stainless steel panel in a safe area until ready for reassembly.Next, you must remove the black plastic cover which is stillremaining on the door in order to get to the springs. There are 2 screws that hold the plastic cover which are difficultto access without removing the side and bottom trim of the microwave opening. The spring was easy to replace at this point and didn't require any tools; just observe when takingthe broken one off, plus you can use the other spring as a go by. Replace the black plastic cover, the bottom trim, theside trims and the stainless door panel and it's complete!
